FIELD: chemistry.
SUBSTANCE: method of manufacturing a fibre-containing element includes the following stages: supply of fibres, at least, some of which are the first fibres, for instance: mineral fibres, polymer fibres, cellulose fibres or other types of fibres, in an amount from 3 wt % to 98 wt % of the total weight of initial materials in the form of an accumulated covering; supply of a binding agent in an amount from 1 wt % to 30 wt % of the total weight of the initial materials, subjection of the accumulated covering from the fibres to the process of the fibre untangling; weighing the fibres in the main air flow; mixing the binding agent with the fibre before, during or after the process of the fibre untangling; supply of the filling agent, for instance, a fire retardant, in an amount from 1 wt % to 55 wt % of the total weight of the initial materials; addition of the filling agent at any suitable stage of the method realisation, for instance, before, during or after the process of the fibre untangling; accumulation of the mixture of fibres, the filling agent and the binding agent and pressing and thermal fixation of the mixture to obtain a consolidated composite material with a density from 120 kg/m3 to 1000 kg/m3.
EFFECT: claimed method can be used to manufacture homogenous composite materials.
